Scientists Develop a Hornless Cow Through Gene Editing

Researchers have developed a method to remove dairy cows’ horns through gene editing. The team inserted a gene from the naturally hornless Angus breed to create hornless Holsteins. Have they developed a new type of cow, or are they just speeding up the breeding process? Jennifer Kuzma, Genetic Engineering and Society Center, discusses the future of biotechnology in agriculture, what defines a “genetically modified organism,” and how these technologies might be regulated.
